MARMADUKE MATTHEVS, OF TORONTO, ONTARIO, CANADA.

WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 322,946, dated July 28, 1885.

Application filed September 525. 1884. (No model.) Patented in Canada October 1, 1884, No. 20,323.

To all whom it may concern.-

Be it known that l, MARMADUKE MAT- THEWS, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, artist, have invented a certain new and useful Water-Heater and I do hereby declare that the following is afull, clear, and exact description of the same.

The object of the invention is to devise an apparatus in which water may be boiled and cooking performed by the action of a coal-oil or gas burner without wasting, to any appreciable extent,the heat produced by the action of the burner; and it consists, essentially,first, in a burner having one or more deflectors arranged to direct the flame of the burner against the sides of the flue extending from the burner to a point above the level of a boiler arranged to encircle the said flue, and, secondly,

in placing a coil of pipe immediately over the 1 top of the flue, so as to form a continuation thereof and utilize the heat therefrom for the purpose of warming the water contained with in the coil which passes from the interior of the boiler through heating pipes or radiators, and returning into the boiler in accordance with the ordinary hot-water-warming system.

The drawing represents a sectional elevation of my'improved heater.

A is aburner having a central air-tube, a, and an annular air-space, 12, formed around the tube a between it and the wick c.

. B is a deflector supported in the top of the alldlllbt) a, and extending over the air-space b and wick 0, so that the air ascending up the air-space b supplies the flame from the wick c with fresh oxygen, and at the same time assists in directing the flame against the sides of the flue G, which, as shown, is larger in diameter immediately around the burner.

D is a small deflector suspended above the deflector B, immediately over a hole or holes made in the deflector B,for the purpose of permitting the air from the air-tube a to enter the flue O. This deflector D directs the air so admitted toward the sides of the flue O, and in this way furnishes fresh oxygen to the interior of the flame, at the same time keeping the center of the flue cooler than its sides,against the full effect of the flame toward heating the flue 0, around which is placed a boiler, E,arranged to contain the water.

It will be noticed that the deflector B of the burner A is directly over the air-space b, and that it serves to spread the flame outward against the sides of the flue O, which flue is greatly enlarged in diameter on a plane passing through the deflector, thereby offering a more extended heating-surface than could be otherwise procured. The air admitted under the deflector D serves to further spread the flame, as shown by the arrows, and cause it to remain for a greater length of time in contact with the sides of the flue, thereby utilizing the heat of the flame to the best advantage.

It will also be seen that the flue O,gradually diminishing in size toward the top, tends to keep the heated gases and products of combustion rising thr jugh the fine in contact with the sides thereof until they escape into the casing, the coolest portion of the air passing through the center of the flue forcing the hottest part of the air and products of combustion against the sides.

F is a coil of pipe suspended, as indicated,

immediately over the top of the flue G. This coil F connects with the interior of the boiler E at its top, as shown, and is also connected to the bottom of the boiler, as indicated, so that circulation through the coil and boiler is maintained when the top of the boiler is closed and the connections made. By placing acoil, F, in the position indicatedthat is to say, immediately over the top of the flue, and within a casing, G, which leads to the chimney or some other convenient point-the full benefit and effect of the flame are secured, and no heat wasted, all the heat from the sides of the flue O radiating therefrom and heating the water contained within the boiler E, while the heated gases and smoke escaping from the top of the flue are utilized for heating the water contained within the coil F.

The advantages obtained by the use of my burner, in connection with the boiler and coil, as above described, not to be obtained by the use of an ordinary burner, are as follows: first, a more extended heating-surface; second, a greater heating medium, and, third, by the tube gradually narrowing toward its exit from its enlarged portion, and the burner ICO having deflectors, each arranged relatively to the position it occupies in the tube, the flame is kept longer in contact with the sides of the tube than could be obtained by any other construction of burner.

I am aware of the Patents Nos. 29,769, 113,567, and 213,926, and make no claim to the constructions shown therein as forming a part of my invention.

What I claim as my invention is- 1. A combined boiler and heater consisting of a water-vessel provided with a flue having a globular enlargement formed therein above the bottom of said water-vessel, and having a water-space surrounding and extending below said globular enlargement, in combination with a burner provided with a deflector to spread the flame toward the sides of the said enlargement of the flue, as and for the purposes set forth.

2. A combined boiler and heater consisting of a water-vessel provided with a flue having a globular enlargement above the bottom of said vessel, near its base, the sides of said en- I a second deflector, D, immediately above,and

an air-space, 1), between the air-tube a and wick c, in combination with the deflector B and flue or chimney G, carried through the boiler E, substantially as and for the purpose specified.
